High [CVE-2026-53790] rsync < 3.5.0 Command Injection via Multiple Code Paths
CVE-2026-53790Source published Source updated
rsync before 3.5.0 contains multiple command and argument injection vulnerabilities that allow attackers to execute arbitrary commands by supplying malicious input through several code paths, including the RSYNC_CONNECT_PROG environment variable, daemon hooks, the rsync-ssl wrapper, and remote-shell command newline injection. Attackers can inject shell metacharacters or newline characters into unsanitized user-supplied values such as hostnames and hostspecs to execute arbitrary commands under the privileges of the rsync process or the invoking user. This Important vulnerability in rsync allows for remote command injection due to insufficient sanitization of user-supplied input across multiple code paths. While the attack complexity is high, successful exploitation could lead to arbitrary…

- Mitigation guidance
- Do not set RSYNC_CONNECT_PROG or pass untrusted hostnames/paths into rsync / rsync-ssl. If rsyncd is required, omit pre-xfer/post-xfer/early exec unless the command ignores client-controlled RSYNC_* values, and restrict TCP/873 to trusted clients
